EMIL ANDERSON, OF NEW YORK, N. L, ASSIGNOR TO TEE UNIVERSAL TURBINE CQIiEPANY, OE JERSEY CITY, NEW JERSEY, A CQRPOR-ATION OF NEW JERSEY.

TURBINE.

To all whom it may concern:

Be it known that I, EMIL AnnnizsoN, a citizen of the United States of America, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Turbine-Engines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in fluid pressure turbines, and its object is to provide a simple, compact and eiiicient apparatus of this character.

I will describe my invention in the follow ing specification and then point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is a sectional side elevation of a turbine embodying the present invention. Fig. 2 is a sectional plan view on an enlarged scale showing some of the parts of this apparatus somewhat in detail. In Fig. 8 the turbine shown in Fig. 1 is shown in sectional end elevation.

Like characters of reference designate corresponding parts in all of the figures.

10 designates an annular frame upon which the other parts of the apparatus are supported. This is open at the bottom as at 11 so that the exhaust motive fluid may pass out through it and through the base upon which it stands, to the air or to a condenser. To the sides of this annular frame are ailixed side plates 12 and 13 each of which is provided with a bearing and with a stufiing-box for the rotor shaft 1%. The hub 20 is keyed to this shaft. From it eX- tends a ribbed flange 21 from which projects an annular shoulder 22. A rim 23 is fastened on the periphery of the flange 21. These parts form an annular trough-like structure open at the side. In this trough are bands 2% of sheet metal suitably spaced apart to divide the trough into a plurality of channels, which are concentric if the bands are of separate circular pieces, or spiral if a continuous strip is used to divide the space within the trough into channels. In either case however these channels are parallel or nearly so. The sheet metal is preferably corrugated so as to make these channels wavy.

The side plate 13 is constructed to form an annular motive fluid chest 15 with which the supply pipe 16 is connected. At one or Specification of Letters Patent. f a'fig f-gd R1 19 1'3143 Application filed August 13, 1912.

preferably more places the outside of this chest is carried inward as at 1'7, to meet the face of the open side of the rotor trough. At each of these thickened portions is a cylindrical sleeve-valve 18 which may be actu ated by a handle 19. These valves are arranged to shut oif the motive fluid or to admit it to the rotor either through an expansion nozzle 25 or a similar nozzle 26 in clined in the opposite direction.

In advance of the nozzle 25 is an expansion chamber duct 2'? formed in the thickened part of the fluid pressure chest. From Fig. 3 it may be seen that the transverse width of the nozzle 25 is considerably less than that of the rotor-trough and that the expansion duct 27 is at one end of about the same width as that of the nozzle 25 and at the otherend is as wide as the rotortrough. The nozzle 26 may be as wide as the rotor-trough.

In the operation of this apparatus, the motive fluid from the supply-pipe 16 enters the annular chest 15 and from thence passes through the valves 18. If the latter are opened in such a direction as to allow the fluid to pass through the nozzles 25, which is the condition present for running forward, the fluid enters a part only of the annular channels between the bands 24:. This of course has a tendency to impel the rotor. as the fluid expands, some of its passes outthrough the chamber 27 and back into the other channels of the rotor where it does further work.

No expansion chambers or ducts are provided with the nozzles 26. This is because these nozzles are for reversing the rotor which usually occurs infrequently and for comparatively short periods so that the highest efiiciency is not required.

What I claim is:

1. In a turbine, a rotor having a troughlike structure open at one side, means for dividing the rotor-trough into a plurality of channels, and a member adjacent to and covering a portion of the rotor trough, said member being constructed to form a nozzle for admitting motive fluid into said channels obliquely.

2. In a turbine, a rotor having a troughlike structure open at one side, means for dividing the rotor-trough into a plurality of channels, and a member adjacent to and covering a portion of the rotor trough, said member being constructed to form a nozzle for admitting motive fluid into some of said channels obliquely, and an expansion duct for leading motive fluid from some of the channels to others.

3. In a turbine, a rotor having a trough- ,llke structure open at one side, bands in said trough spaced apart to divide the trough into a plurality of substantially concentric channels, and a member adjacent to and covering a portion of the rotor trough, said member being constructed to form a nozzle for admitting motive fluid into said channels obliquely.

' l. In a turbine, a rotor having a troughlike structure open at one side, bands of corrugated metal in said trough spaced apart to divide the trough into a plurality of substantially concentric wavy channels, and a member adjacent to and covering a portion of the rotor trough, said member being constructed to form a nozzle for admit-ting motive fluid into said channels obliquely.

5. In a turbine, a rotor having a troughlike structure open at one side, bands of corrugated metal in said trough spaced apart to divide the trough into a plurality of substantially concentric wavy channels, and a member adjacent to and covering a portion of the rotor trough, said member being con structed to form a nozzle for admitting motive fluid into some of said channels obliquely, and an expansion duct for leading motive fluid from some of the channels to others.

6. In a turbine, a rotor having a trough like structure open at one side, bands in said trough, spaced apart to divide the trough into a plurality of substantially concentric channels, and a plurality of stationary members disposed at intervals about ,the rotor, adjacent to and covering portions of the open side of the rotor trough, each of said members being constructed to form a pair of nozzles for admitting motive fluid into said channels in opposite oblique directions.

7. In a turbine, a rotor having a troughlike structure open at one side, bands of corrugated metal in said trough, spaced apart to divide the trough into a plurality of substantially concentric Wavy channels, and a plurality of stationary members disposed at intervals about the rotor, adjacent to and covering portions of the open side of the rotor trough, each of said members being constructed to form a forward nozzle and a reverse nozzle, said forward nozzles being arranged to admit motive fluid into some of said channels and said members being c011- structed to form expansion ducts in advance of the forward nozzles for leading motive fluid from some of the channels to others.

In testimony whereof, I have hereunto set my hand this 1st day of August, 1912, in the presence of two Witnesses.
